US officials have announced that a man in his fifties has been confirmed as the first person to have a coronavirus in the United States capital. District of Columbia Speaker Muriel Bowser said Saturday that the patient had begun to show symptoms of the Covid-19 virus at the end of February. He was hospitalized on Thursday and appears to have not traveled abroad and had no contact with people coming from states affected by the coronavirus. Local authorities have begun investigating the contacts and movements of the infected person in order to identify other possible cases and prevent the spread. US President Donald Trump has said he is not worried that the coronavirus is approaching the White House after officials said a person attending a Trump conference has been confirmed to be infected with the new virus. Officials have no plans to cancel the rallies, including the annual Cherry Blossom Festival, which begins March 20 and attracts thousands of tourists, writes The Associated Press. Authorities said they are prepared to monitor the public health situation and that there is coordination among several agencies.
